Hunters

It's the group that tries to defeat the demons that the Summoners create. The main team is formed by Takashi, Kurori, Ryôji and Onitsuki.

Origins
After the story that Reiji told the Hunters, the group has existed for a long time. The fight between Hunters and Summoners started long ago. Summoners started to create and use demons on their benefits and the demons killed people, so the Hunters decided to use the power they were given to stop them. On one of those fights, the Hunters defeated the Summoners, but after years, their descendant, Yuichi, started once again to summon demons, so the new group was formed. The ones that created the team were Onitsuki and Takashi, having the others to join soon after.

To become a Hunter, demons must have interfered with that human's life. The moment a demon changes the fate of that person, does something that influences a lot in that person's life, the human can see the demon and gets the power of the Hunters. From that event on, that person will be able to see demons.

Powers
When a person becomes a Hunter, besides being able to see demons, they get a magical weapon that appears whenever they want, and helps them to defeat the demons with its strength. It can be a physical weapon or even being able to use magic.

Other Hunters
The members of the Shinden shrine are Hunters with a weak power, that's why they stay there gathering information and protecting the shrine instead of fighting against the Summoners. The only one there with great power as a Hunter is Rise.
